Constructing a Square an Ancient Indian Way Activity
Cynthia J. Huffman Ph.D.
In this activity students use string to model one of the ways that was used in ancient India for constructing a square. The construction was used in building a temporary fire altar. The activity is based on a translation by Sen and Bag of the Baudhāyanaśulbasūtra.

Constructing a Square Indian Fire Altar Activity
Cynthia J. Huffman Ph.D.
In this activity, we will model constructing a square fire altar with a method similar to one used by people in ancient India. The fire altars, which were made of bricks, had various shapes. Instructions for building the altars were in Vedic texts called Śulbasūtras. We will follow instructions for constructing a square gārhapatya fire altar from the Baudhāyanaśulbasūtra, which was written during the Middle Vedic period, about 800500 BC.

Euler Construction Activity
Cynthia J. Huffman Ph.D.
Original sources of mathematics provide many opportunities for students to both do mathematics and to improve their problem solving skills. It is also interesting to explore original sources in new ways with the use of technology. In this activity, students can gain experience with dynamic geometry software and enhance their geometric intuition by working through a construction given by Euler in 1783.

Place Value in Primary Sources Activity
Cynthia J. Huffman Ph.D.
An activity for student to examine the use of placevalue in the HinduArabic numeration system from a historical viewpoint by looking at primary sources.

Problem Solving Practice with Problems from Fibonacci's "Liber Abbaci"
Cynthia J. Huffman Ph.D.
In this activity, problem solving skills are practiced using two wellknown problems from Fibonacci's worldchanging book "Liber Abbaci". Students are also asked to reflect on the differences and similarities between their solutions and those of Fibonacci. The two problems are the famous rabbit problem which led to what is now know as the Fibonacci sequence and the 30 birds for 30 denarii problem, which is not as wellknown to the general public.
